Life when you start getting 10k steps/day and 8 hours of sleep every night and quit watching porn, smoking weed & drinking alcohol and genuinely reach flow state.
you can fuck up pretty bad at most ages and still have your life work out, but the people i know who wound up in bad relationships or with health downturns while single in their 30s mostly missed the boat on kids.
for all the talk of permanent records and getting into the right college when you’re young, it turns out that career paths are winding and forgiving across the course of a lifetime, but there is actually a relatively short window to find a partner and start a family.
